Abstract:
A N-terminal modified PEG(polyethylene glycol)-TRAIL(tumor necrosis factor related apoptosis inducing ligand) is provided to reduce liver toxicity, increase the in vivo retention time, and enhance solubility and stability in solution and pharmacokinetic profiles of TRAIL, so that it is useful for prevention and treatment of proliferative disease and autoimmune disease. A N-terminal modified PEG-TRAIL having non-toxicity to the liver is prepared by linking PEG or PEG derivatives specifically to the N-terminal of TRAIL, wherein PEG is selected from methoxy polyethylene glycol succinimidyl propionate, methoxy polyethylene glycol N-hydroxysuccinimide, methoxy polyethylene glycol aldehyde, methoxy polyethylene glycol maleimide and multi-branched type polyethylene glycol, and the TRAIL contains a zipper amino acid array inducing trimer formation or a terminal group for facilitating the separation and purification.
Abstract:
A biotin and biotin polyethylene glycol-linked GLP-1 derivative is provided to be usefully used for preventing or treating diseases caused by excessive secretion of insulin, lowering of glucose in plasma, inhibition of stomach or intestine motion, inhibition of an empty stomach or intestine, or inhibition of food intake, type 2 diabetes, obesity and irritable colon syndrome. A GLP-1 derivative in which biotin and biotin-polyethylene glycol are selectively linked to No. 26 lysine residue and No. 34 lysine residue is represented by the formula(2), wherein the biotin-polyethylene glycol is represented by the formula(1) having a molecular weight of 3,400. A method for preparing the GLP-1 derivative comprises the steps of: (a) adding biotin, biotin-polyethylene glycol and GLP to a buffer solution and an organic solvent to be subject to reaction; (b) storing the reaction mixture obtained from the step(a) under a certain temperature for a certain period of time; (c) removing non-reacted reaction products after the reaction completion of the step(b); and (d) isolating GLP-1 in which the biotin and biotin-polyethylene glycol are linked from the non-reacted products-removed products and purifying them. A pharmaceutical composition for preventing or treating diabetes or obesity comprises the biotin and biotin polyethylene glycol-linked GLP-1 derivative.
